In 1997, the American Diabetes Association (ADA) and the federal government lowered the standard for diagnosing diabetes from a fasting blood glucose level of 140 mg/dL to 126 mg/dL.7. What is the proportion of people who are considered have diabetes and they were not considered have diabetes before 1997
Answer:
10 percent
Step-by-step explanation:
- Before 1997, people with a minimum FBGL of 140mg/dl were diagnosed as diabetic
- After 1997, people with a minimum FBGL of 126mg/dl were diagnosed as diabetic
- What is the proportion of people who were not considered diabetic before 1997 but are now considered diabetic (after 1997)?
140 - 126 = 14
In percentage, this proportion is = 14/140 × 100
= 10%
Hence, 10% of the people who were not considered diabetic before 1997 are now or will now be considered diabetic.

Answer:
i think 20 is above 12 and 17 under 30 and 36 is on top of 20 the rule is .50(x) +2
Answer:
Step-by-step explanation:
c = 0.5t + 2
12 = 0.5t + 2 ⇒ 0.5t = 10 ⇒ t = 20
c = 0.5(30) + 2 ⇒ c = 17
20 = 0.5t + 2 ⇒ 0.5t = 18 ⇒ t = 36

Find x if a = 13 and C = 47.
Answer:45.167
Step-by-step explanation:
So you're using the Pythagorean theorem which is a^2 + b^2 = c^2... so if you don't have b you can manipulate the equation. That equation is c^2 - a^2= b^2, so you square 47 which is 2209 and then square 13 which is 169... you do 2209-169 and that equals 2040, then you do the square root of that which is 45.166359 that can be simplified to 45 or two decimal points 45.167. Hope that Helped! :)

Find f (x )if f apostrophe apostrophe (x )equals x to the power of negative 2 end exponent comma space x greater than 0 comma space f (1 )equals 0 and f (2 )equals 0.
Step-by-step explanation:
Given [tex]g'(x) = g^{-2}, x> 0\ g(1) = 0 \ and \ g(2) = 0[/tex]
To get g(x), we will have to integrate g'(x)
[tex]g(x) = \int\limits {x^{-2}} \, dx\\ g(x) = \frac{x^{-2+1}}{-2+1} + C\\ g(x) = -x^{-1} + C\\g(x) = -x^{-1} + C\\[/tex]
If g(1) = 0, this means at x = 1, g(x) = 0
0 = -1⁻¹ + C
C= 1
Substitute C = 1 into the function
g(x) = -x⁻¹ + 1
If g(2) = 0, this means at x = 2, g(x) = 0
0 = -2⁻¹ + C
C= 2⁻¹
C = 1/2
Substitute C = 2 into the function
g(x) = -x⁻¹ + 1/2

Which value is a solution of the rational equation that must be discarded because of the context?

OC. X = -18

tum. All rights reserved.
The value that is a solution of the rational equation that must be discarded because of the context is (b) x = -10
The equation is given as:
[tex]\frac 1x + \frac{1}{x + 18} = \frac{1}{40}[/tex]
Take the LCM
[tex]\frac{x + 18 + x}{x(x + 18)} = \frac{1}{40}[/tex]
This gives
[tex]\frac{2x + 18}{x(x + 18)} = \frac{1}{40}[/tex]
Cross multiply
[tex]40(2x + 18) =x(x + 18)[/tex]
Expand
[tex]80x + 720 =x^2 + 18x[/tex]
Collect like terms
[tex]x^2 + 18x - 80x -720 = 0[/tex]
[tex]x^2 - 62x -720 = 0[/tex]
Using a graphing calculator, we have:
[tex]x = 72\ or\ x =-10[/tex]
The value of x cannot be negative, because of the context.
So, the value that is a solution of the rational equation that must be discarded because of the context is (b) x = -10

Answer:
x = 46
Step-by-step explanation:
64-18=46
Answer:
x=46
Step-by-step explanation:
Subract the 18 from both sides, canceling the 18 from the 'x + 18' and leaving you to subtract 18 from 64, resulting in 46.
